Which items should be inspected on arresting gear wires and hooks?

• A. Wear, fraying, corrosion, hook engagement, and mounting integrity.
• B. Only wear and corrosion.
• C. Only hook engagement.
• D. Only mounting integrity.

Answer: (A)

Arresting gear must function reliably under high dynamic loads, so inspections target every way the system could fail to arrest an aircraft. Wear and fraying reveal material loss and surface damage that can grow into fractures under load. Corrosion weakens metal, reducing strength and increasing the risk of sudden failure. Hook engagement covers whether the arresting hook properly catches and holds the wire, which is essential for a secure arrest; if engagement is poor, the system may fail to arrest or cause damage during capture. Mounting integrity ensures the wires and hooks are firmly attached to their supports and deck structures; a loose or compromised mounting can allow movement, misalignment, or failure to transfer load correctly. Because each of these areas addresses a different potential failure mode—material degradation, insecure connections, and proper alignment—the inspection should cover all of them. Focusing on only one aspect could miss a separate, critical issue that could compromise safety.
